Ku bikoresho by'ikoranabuhanga byo mu nganda, ihame ryo gupima flowmeter ya electromagnetic ni itegeko rya Faraday ryo kwinjizwa kwa electromagnetic. Imiterere ya flowmeter ya electromagnetic igizwe ahanini na sisitemu ya magnetic circuit, umuyoboro wo gupima, electrode, igishishwa, lining na converter. Ikoreshwa cyane cyane mu gupima ingano y'amazi atwara imizigo n'ibishishwa mu miyoboro ifunze. Harimo aside, alkali, umunyu n'ibindi bintu bitwara amazi menshi cyane. Iki gicuruzwa gikoreshwa cyane mu nganda za peteroli, chimique, metallurgy, imyenda, ibiribwa, imiti, gukora impapuro n'izindi, ndetse no kurengera ibidukikije, gucunga umujyi, kubaka amazi n'ahandi.
Mu gihe cyo gukoresha icyuma gipima amashanyarazi, hari ibibazo bimwe na bimwe by’ibikoresho bizabura. Ubusanzwe hari ubwoko bubiri bw’ibibazo mu mikorere: bumwe ni ukunanirwa kw’igikoresho ubwacyo, ni ukuvuga kunanirwa guterwa no kwangirika kw’ibice cyangwa ibice by’igikoresho; ubwa kabiri, kunanirwa guterwa n’impamvu zo hanze, nko gushyiraho nabi, guhinduranya amazi, gushyiramo no gupima, n’ibindi.
Iyo icyuma gipima amashanyarazi cyananiwe, akenshi tuba tugomba gusesengura igice kirimo amakosa hanyuma tugashaka uburyo bwo gukemura ikibazo.
1. Amakosa asanzwe ya electromagnetic flowmeter – electromagnetic flowmeter nta kimenyetso cy'umuvuduko gitanga
Ubu bwoko bw'inanirwa bukunze kugaragara mu gihe cyo gukoresha, kandi impamvu muri rusange ni izi zikurikira:
(1) Ingufu z'igikoresho ntizisanzwe;
(2) Ihuza ry'insinga n'umusaruro w'ikibaho cy'amashanyarazi ntibisanzwe;
(3) Uruzi rw'amazi ntiruhuye n'ibisabwa mu gushyiraho;
(4) Ibice by'icyuma gipima ibintu byangiritse cyangwa hari agace gafata ku rukuta rw'imbere rw'igipimo;
(5) Ibice byangiritse bya converter
Uburyo bwo gukemura ikibazo?
Niba ibi bibaye, banza urebe niba umuriro w'igikoresho ufite ikibazo, wemeze ko umuriro w'amashanyarazi uhujwe, urebe niba ingufu z'amashanyarazi zisohoka ari zisanzwe, cyangwa ugerageze gusimbuza umuriro wose w'amashanyarazi kugira ngo umenye niba ari mwiza. Genzura ko insinga zimeze neza kandi zihujwe neza. Genzura icyerekezo cy'amazi n'amazi ari mu muyoboro yuzuye. Niba nta mazi ari muri sensor, uzakenera gusimbuza umuyoboro cyangwa guhindura uburyo bwo kuwushyiraho. Gerageza kuwushyiraho uhagaze.
2. Ikimenyetso cy'icyuma gipima amashanyarazi kirimo kugenda gigabanuka cyangwa ikimenyetso kigahita kigabanuka
Inyinshi muri izi nzitizi ziterwa n’ingaruka z’igikoresho gipima cyangwa ibidukikije byo hanze, kandi ikosa rishobora gukurwaho ubwaryo nyuma yo gukurwaho kw’ingaruka mbi zo hanze. Kugira ngo harebwe neza ko gupima ari ukuri, ibyo binaniranye ntibishobora kwirengagizwa. Mu bidukikije bimwe na bimwe by’umusaruro, bitewe n’ihindagurika rikomeye ry’umuyoboro wo gupima cyangwa amazi, ikibaho cy’umuyoboro w’amashanyarazi kizarekurwa, kandi agaciro k’umusaruro na ko gashobora guhinduka.
Uburyo bwo gukemura ikibazo?
(1) Emeza niba ari yo mpamvu y'imikorere y'ibikorwa, kandi amazi aratera. Muri iki gihe, icyuma gipima imiterere y'amazi kigaragaza gusa imiterere y'amazi, kandi ikibazo gishobora gukurwaho ubwacyo nyuma y'uko gutera amazi kurangiye.
(2) Ihungabana ry'amashanyarazi riterwa n'imigezi yo hanze, nibindi. Reba niba hari ibikoresho binini by'amashanyarazi cyangwa imashini zisudira amashanyarazi zikora mu buryo bw'ikoranabuhanga, kandi urebe neza ko igikoresho gihagaze neza kandi ko ibidukikije bigikoreramo ari byiza.
(3) Iyo umuyoboro utuzuyemo amazi cyangwa amazi arimo utubumbe tw’umwuka, byombi biterwa n’impamvu z’imikorere. Muri iki gihe, umutekinisiye ashobora gusabwa kwemeza ko agaciro k’umusaruro gashobora gusubira ku rugero nyuma y’uko amazi yuzuye cyangwa utubumbe tw’umwuka dutuje.
(4) Urubaho rwa serivise y'umuyoboro w'amashanyarazi ni imiterere y'inyongera. Bitewe n'ihindagurika rikomeye ry'umuyoboro w'amazi cyangwa amazi uri aho hantu, amashanyarazi y'umuyoboro w'amashanyarazi akunze kurekurwa. Iyo adarekuwe, icyuma gipima amashanyarazi gishobora gusenywa hanyuma icyuma gipima amashanyarazi kigakosorwa.
3. Ingingo ya zeru y'ikigega cy'amashanyarazi ntabwo ihamye
Isesengura ry'Impamvu
(1) Umuyoboro ntuba wuzuyemo amazi cyangwa amazi arimo utubumbe tw'umwuka.
(2) Mu buryo bufatika, byitezwe ko nta mazi asohoka mu ipompo y'umuyoboro, ariko mu by'ukuri hari amazi make asohoka.
(3) Impamvu zitera amazi (nk'uburyo amazi adakora neza, ihumana ry'amashanyarazi, n'ibindi).
(4) Ubushyuhe bw'urukiramende rw'ikimenyetso buragabanuka.
Uburyo bwo gukemura ikibazo?
Ni ngombwa kugenzura niba icyuma cyuzuye imiyoboro kandi niba hari utubumbe tw’umwuka muri icyo cyuma. Niba hari utubumbe tw’umwuka, icyuma gikuraho umwuka gishobora gushyirwa hejuru y’utubumbe tw’umwuka. Uburyo bwo gushyiraho igikoresho bushobora kandi guhindurwa kugira ngo gishyirweho mu buryo butambitse. Reba niba igikoresho gifite ubutaka bwiza. Uburinzi bw’ubutaka bugomba kuba buri munsi ya 100Ω cyangwa bungana na; ubushobozi bwo gutwara amashanyarazi bw’icyuma gitwara amashanyarazi ntibugomba kuba munsi ya 5μs/cm. Niba icyuma gikwirakwira mu muyoboro wo gupimisha, kigomba gukurwaho igihe. Irinde gushwanyaguza umugozi mu gihe cyo gukuraho.
